Very fake.
Obviously CG, I can tell from the way the texture and lighting is.
The acting is terrible.
The camera work is purposely shoddy, and going out of focus too much.
You ever seen a real video from an air show or something? None of them look like this. I heard no wind, no people breathing. The camera seemed too 'professional grade' for what this video is supposed to be. And all the sounds sounded dubbed in (Because they were).
Also, when have you ever seen anyone scream "RUUUUUUUUN" so cheesily, so close to a soon to be wreck, and stay PERFECLTY ON TARGET with their camera? (When he can't even stay on it when it's moving in the air hundreds of feet away.)
